Frequently Asked Questions
What is the Enwitec Surge Protection Box?
The Enwitec Surge Protection Box is a DC-side string combiner box with an integrated Type I+II / BC surge arrester. It combines up to 4 strings of an MPP input and protects the PV system on the DC side against partial lightning currents and switching overvoltages up to 1000 VDC.
Which systems is the surge protection box suitable for?
It is designed for PV systems with one MPP input and up to 4 strings. The rated current is 64 A DC, the maximum design current Isc is 80 A DC, and the rated voltage is 1000 VDC. The input and output terminals accept cable cross-sections up to 16 mm².
What surge protection does the box offer?
A combined Type I+II / BC arrester is installed. Type I dissipates high-energy partial lightning currents, while Type II also protects against switching overvoltages. The status of the arrester can be monitored remotely via the remote signaling contact (2.5 mm² terminals). String fuses are not included.
